' CONDUCTOR SUPPORT.

My invention relates `to conductor sup-4 ports and particularly for the supportingof trolley wires used in the operation of ,electric railways, and its main object is the connecting or supporting of the ends of two trolley wires in adjacent relation so as to constitute as near as possible, a continuous conductor.

My invention resides in the new and novel construction, combination and relation of the various parts hereinafter fully disclosed and set forth in the drawing accompanying this specification. i

In the drawing: l

Fig. l is a top plan view of my invention.v Fig.2.is ya side View in elevation and partial section of myinvention, showing two trolley wires in position, but before any ,strain is permitted,tending to separate the same. l Y v 1 Fig. 3v is a sectional view on the line 3-3 of Fig. 2.

Fig. 4; is a side view in elevation and par- ,tial section of my invention, showing the trolley conductors held thereby and under strain, tending to separate the same.

. Inthe preferred embodiment of my invention,fI employ ay body member l provided j with a tubular recess 2 extending throughthe bodymember in a longitudinal direction and adaptedto receivethe ends of a trolley wire,. or other conductor 3 for the` purpose of holdl ing the same in a iixed and electricallylconnected relation. The body member is also provided with enlarged portions 4 which in turn are each provided with a recess 5 having side openings 6. These side openings may be upon opposite sides of each enlarged portion fl or only on one side, as their function is to permit the placing or removal of the locking dogs 7, which are composed preferably of steel provided with teeth 8. Each recess 5 has an opening 9 into the tubular channel 2 whereby the locking dogs 7 may be brought into engagement with the ends of the conductors 3. In order to adjust the locking dogs relative to the trolley conductors 3 and to prevent their removal from the 4recess 5 only at will, I employ two adjusting nuts l0 having threaded engagement with the body member 1 whereby they may be moved toward or away from the conductors 3 and thereby move the locking dogs 7 toward the conductor or permit the removal of the locking dogs away from the conductor. In other words, the nuts 10 adjust the relation of the locking dogs 8 relative to the conductor 3. The body member is also provided with a web 11 at each end for stii'ening and strengthening the same. l Y

The ends of the adjusting nuts l0 which engage the vdogs 7 are preferably rounding, so as to permit the dogs 7 to rock freely or pivot about the end of the adjusting nuts whereby the dogs 7 act as a cam or wedge between the adjusting nuts l0. and the conductors 3 when there is a tendency for 'the conductors 3 to pull apart, as shown by the arrows in Fig. 4. Itwill be noted that thev recesses 5 are provided with sidewalls l2 below the openings 6 which together with the end of the adjusting nuts 10 prevent the removal of the dogs y j To install my invention, the ends of the conductor 3 are forced intofthe tubularv channel 2 until the ends pass the dogs 7 and abut against each other as near the center of the body member as possible.V .Inl order to permit the positioning of the conductorsv 3, it is necessary that the adjusting nut 10 ing dogs 7 to rise :and allow the conductors to pass the same. y As soon as the conductors are positioned, the adjusting,nutsaref screwed down into engagement with theY dogs 7, moving them, into firm engagement with the ends of j the f conductor 3. This engagej ment 4canbe varied according to the force exerted upon the adjusting nut 10. As soon as strain is brought upon the conductors 3.

tending to separate them, the teeth 8 of the v dogs 7 will bite into the conductor 3 and the dogs 7 will be rotated or pivoted about the end of the adjusting nut 10 and 'tend to assume the position shownin Fig. 4. From this, it will be noted that the greater the strain tending to separate the conductors 3, the greater will be the tendency for the dogs 7 to resist the separation of the conductors 3.

It is quite apparent that when the end of the dogs 7 engages the inner side walls of the recess 5, that any further movement of the conductors 3 away from each other must either force the wall 13 downward or shear the metal of the conductor. In other words, the engagement of the dogs 7 with the walls of the recess, as shown in Fig. 4, amounts to a positive lock to the extent of the strength o'i' the device or the resistance to shearing of the conductor 3.

There are, 01"' course, many modifications which will suggest themselves to one skilled in the art and I do not Wish to be limited otherwise than by my claims.

I claim 1. A conductor splicer comprising a body member and a longitudinal recess therein to receive the end of the conductor', a movable dog arranged to project into the recess and engage the conductor in such manner that the conductor may be positioned within the recess but not Withdrawn and adjustable means about which the dog pivots for moving the dog towards the conductor.

2. A conductor splicer comprisinga body member and a longitudinal conductor-receiving recess therein, a pai-'r of movable dogs arranged to project into the recess and engage the surface. of the 'eii'ds of the conductor in such manner that the' end of the conductorsinay be positioned Within the recess in adjacent relation but not Withdrawn and adjustable means about which the `clogs pivot for moving the dogs t'ovvards the co`nductois Vand preventing them moving away from the conductors. A

3. A conductor splicer coi'nprising 'a body member a longitudinal conductor-receiving recess therein, an enclosure, an opening thereto through the side of tlle body m'embei" and through which a dog may be positioned Within or removed Aat will from the recess and opening leading from the en'- closure into the recess, a movable dog in the enclosureadapted to project into the recess and engage the conductor and permit the positioning of vtlie conductor in the recess but prevent its being Withdrawn.

4; A conductor splicer comprising a body member and a longitudinal conductor-'ree ceiving recess therein, an enclosure, a side opening thereto and an opening leading from the enclosure into the recess, a longitudinally movable and removable dog in the enclosure adapted to project into the recess and engage the conductor and permit the polsitioning of the conductor in the recess but prevent its being Withdrawn.

5. A conductor splicer comprising a body member and a longitudinal conductor-receiving recess therein, a pair o'll enclosures an'd access to each enclosure, an opening from each enclosure leading into the recess and a movable dog in each enclosure projecting into the recess to engage the surface of the conductor ends when positioned Within the recess and arranged to 'prevei'it the conductors being Withdrawn and means to move and maintain the do'gs in engagement with the conductors 'and about which the dogs pivot. l

6. A conductor splicer comprising a body member having a continuous longitudinal recess to receive the ends of conductors, ya pair 'of enclosures and Va dog in each enclosure free to move longitudi-ifnillj'f away from each other a limited 'distance and projecting into the recess and arranged to grip the ends of the coiidi'rctors and manually adjustable means to move the dogs towards the conductors and maintain the dogs in engagement with the conductors.

7. An article of manufacture for attac-lr ment t'o a "conductor to grip and hold the same comprising a bodymember having al recess therein to receive the 'end of the 'cond'uctor, a movable 'dog 'arranged t'o project into the recess and engage the conductor such that the conductor may be 'positioned Within the recess and held against removal by the dog, adjustable means about which the dog4 pivots for moving/tire dog 'toward the conductor and means for attaching hold'- ing means to the body member to vmaintain a tension in the conductor.

In testimony whereof' I ali/ix my signature.
